Question

a convex lens of focal length 12 produce a real image which is 1/3 times of object find the distance of the object from the lens​

Answer 1

Answer:

16cm is the distance of the object

Answer 2

Answer:

1

/v

-1

/u

​ =  1/12

​

u−v

/v=1/12  -(1)

 m=  -v/u =3

v=−3u

using equation (1)

−u×3u

/u+3u

​ =  12

/1

​u=−16cm

∴v = 48 cm

So u−v= 64 cm
